People use stainless steel for various reasons, including its mechanical properties and appearance. However, for most, the first thing that comes to mind is its resistance to corrosion, which makes it highly desirable for many applications. For example, stainless steel is used in the food, medical, construction, automotive, and marine industries, to name a few.

Stainless steel is often more expensive than carbon steel so choosing the right abrasive is essential. Doing so can significantly improve production efficiency, reduce rework costs, and reduce material waste.

Like carbon abrasives, stainless steel is also carbon-based, but with a significant amount of chromium (minimum 10.5%). Other elements such as nickel and molybdenum are added to improve its characteristics, mainly its resistance to corrosion.

Stainless steel products are generally used in applications that are exposed to very aggressive environments (saline, acid or alkaline environments). This corrosion

On this occasion we have to talk about energy since the process of shot blasting a piece is done by transmitting kinetic energy to an area.

The formula tells us that the kinetic energy is equal to one half of the mass times the speed squared, that is to say that the variables here would be the mass, which is the size of the particle and the quantity that is thrown plus the speed, since either the particles are blown by means of a wheel or by air pressure through nozzles in an airblast system.

The particles are accelerated through these media to transmit that energy and do the cleaning work; Another very important variable is the hardness of the particle, and in the case of steel abrasive, it is defined by the amount of carbon it contains.

Therefore, there are two types of abrasives on the market: low and high carbon steel. But how do we know which one suits us best?

Manufacturers of low carbon shot may claim that their product is better than high carbon shot

What material is more efficient to clean or polish the surface of metal parts?

Here we tell you some details and differences about the abrasives known as "Steel Abrasive" and "Silica Sand"!

The surface treatment of metal parts is essential for future conditioning or work in the workshop. And the abrasives mentioned above can help you give them that perfect finish you need, but which of the two is better to optimize efficiency, speed, quality and cost?

To make the best decision, you must take into account elements such as size, shape, hardness and fragility.

For example, starting with the "Silica Sand", which due to its extreme fragility and thanks to the fact that it is projected by high production equipment, can only be used once since up to 80% of the material turns into dust.

The separator is a key element of any shot blasting system. Usually it is located on top of the storage hopper, this is in charge of removing the contaminants out of the Operational Mix of shot, as well as controlling the size of the retained abrasive and disposing of material such as; very fine abrasive, contaminants removed from parts, etc. With the clean abrasive falls directly into the hopper.

In this way, the efficiency of the separator becomes a crucial parameter in operating costs, as well as the adjustments that must be taken care of within it, such as the extraction of fines from the system and the air flow that passes through it.

Most of the separators have a rotating screen to remove large contaminants and an outlet to a container to deposit all the trash.

The design of the separator varies from machine to machine, but in all, the fundamental principle of operation is the same:

• Extend the abrasive curtain through the separator
• Regulate

Shot blasting, also known as abrasive blasting, is even known by some as "sandblasting" by its English term, although the latter concept refers exclusively to blasting with silica sand. It is a process where an abrasive material is propelled by means of air, water or centrifugal force against a surface.

This method is used to clean, strengthen or prepare surfaces.

There are many variants in the procedure to throw the abrasive medium but the most common is to do it through a machine with wheels, which drive the abrasive against the target, that

To understand the how well, we need to understand well what is sand blast or sandblasting? The definition of this word is understood as “sand under pressure”; however, numerous abrasives in addition to sand can be used in this operation to clean, polish or remove materials and residues from different surfaces.

In areas of abrasives, we have 2 types commonly used:

ARTIFICIAL ABRASIVES

• Aluminum oxide
• Steel shot
• Silicium carbide
• Sodium bicarbonate
• Cut wire
• Garnet
• Copper slag
• Glass pearl
• Plastic abrasive

NATURAL ABASIVES

• Silica sand
• Diamonds
• Quartz
• Corundum

To sandblast, we use compressed air which propels the abrasives at

The environment is an ever increasing imperative, and worldwide concern, its protection is important. Hence company put everything into action to reduce their environmental impact.

That’s why Winoa is committed to protect the environment and is launching different actions such as process waste, investments in water treatment, air treatment and recyclable packaging. Thanks to its internal and external awareness campaigns Winoa has been certified ISO 50001, and ISO 14001, which are the result of a successful and continuous improvement.

“Environment friendly” is not just a concept, but a value Winoa shares, and that we would like to pass on to the next generations.
